Clearly, she's daydreaming. I can only wonder now what could possibly be going through her head to put such an adorably dopey grin on her face and give her want to balance her glasses on her hind hoof.

It's either that or she's looking up at something and is verging on euphoria at the display before her.

Iunno.

'Tis cute and very smoothly drawn. Also fond of the slightly fluffier, more realistic mane style. Now it looks like she's only using half a gallon of hair gel.

In all seriousness though, I can only spot a few imperfections otherwise. Her cutie mark admittedly, is oddly oriented; it would appear nearly inverted were she standing normally. From this position, it should be flipped and rotated slightly, somewhere around 90°. The perspective on the glasses also seems a touch askew.
